If its just leading zero's that you want, you can use this:

value.tostring.padleft("0",2)
value.ToString().PadLeft(2, '0');   // C#

If you have 2 digits, say 25 for example, you will get "25" back....if you have just one digit, say 9 for example, you will get "09"....It is worth noting that this gives you a string back, and not an integer, so you may need to cast this later on in your code.

String formate is the best way to do that. It's will only add leading zero for a single length. 9 to "09" and 25 to "25".

String.format("%02d", value)

Bonus: If you want to add multiple leading zero 9 to "0009" and 1000 to "1000". That's means you want a string for 4 indexes so the condition will be %04d.

String.format("%04d", value)

You can use either of these options:

The "0" Custom Specifier

  • value.ToString("00")
  • String.Format("{0:00}", value)

The Decimal ("D") Standard Format Specifier

  • value.ToString("D2")
  • String.Format("{0:D2}", value)

I don't know the exact syntax. But in any language, it would look like this.

a = 9
aString =""

if a < 10 then 
  aString="0" + a 
else 
  aString = "" + a
end if
